A blocking element is arranged on the output wheel to block a rotational movement, and a guide track having a blocking stop integrated therein and at least one deflection position; the guide track is connected to a pin section, which is movable to a limited degree and which is provided in order to be guided along the guide track upon rotation of the output wheel and to block a rotational movement of the output wheel upon penetrating into the blocking stop. By using the at least one deflection position, the rotative position of the blocking element can be detected during guiding of the pin section by the at least one deflection position. ## Claims ### Claim 1 A gearing arrangement for an actuator device for height adjustment of a vehicle body, the gearing arrangement comprising: an input wheel;
